Description

[Technical Field]

[0001] An embodiment of the present invention relates to a training device, a discharge operation device, a training method, and a discharge operation method. [Background technology]

[0002] The Dam Management Control Processing Facility (hereinafter referred to as "Damcon") system is a system that supports the operation and management of dams. For example, Non-Patent Document 1 published by the Ministry of Land, Infrastructure, Transport and Tourism describes the training function of the Damcon system as follows: "The training process is intended to enable operators to learn operations during floods, such as formulating discharge plans at the start of discharge, determining when to switch to a discharge method, and responding when the Damcon function stops."

[0003] Furthermore, Non-Patent Document 1 states, "This process has the function of simulating how the reservoir behavior and the balancing situation between inflow and outflow will change if the operator inputs the target discharge volume for each future time of discharge for a given inflow volume, or selects the discharge method to be used in the future, and operates the dam using this target discharge volume or discharge method.It also allows the operator to train to respond by manual calculations, etc., assuming that the dam control system's functions have stopped."

[0005] [Non-Patent Document 1] Ministry of Land, Infrastructure, Transport and Tourism, "Dam Management Control and Processing Equipment Standard Design Specifications and Commentary," August 2016 Summary of the Invention [Problem to be solved by the invention]

[0006] Non-Patent Document 1 does not provide any specific description of the specific functions or implementation methods of the "training process," and only provides a minimum explanation of the functions. Furthermore, during an actual flood, operators must execute gate control based not only on information obtainable from the dam control system, but also on the forecast rainfall announced by the Japan Meteorological Agency and action guidelines prepared by each dam. However, Non-Patent Document 1 discloses that a simulation is performed based on information obtainable from the dam control system, which is problematic in that it differs from the actual operations that are performed.

[0007] Therefore, even if an operator undergoes training using the training device described in Non-Patent Document 1, there is a problem in that the training cannot be carried out in accordance with actual behavior.

[0008] The object of this invention was made in light of the above circumstances, and its purpose is to provide technology in a training device that can carry out flood training based on information that will actually be used. [Means for solving the problem]

[0009] The training device according to the embodiment includes an acquisition unit that acquires dam quantity data and a plurality of prediction data corresponding to the dam quantity data from a storage unit, a superposition processing unit that generates superposition data by superimposing one of the plurality of prediction data and the dam quantity data, and a display control unit that controls the output unit to display display screen data including the superposition data. It is equipped with the following. [Brief explanation of the drawings]

[0011] The training device, discharge operation device, training method, and discharge operation method will be described in detail below with reference to the drawings. Note that in the following embodiments, parts with the same numbers perform the same operation, and redundant explanations will be omitted. For example, when there are multiple identical or similar elements, a common symbol may be used to describe each element without distinguishing between them, or a sub-number may be used in addition to the common symbol to describe each element with distinction between them.

[0012] [First embodiment] (composition) FIG. 1 is a block diagram showing an example of a schematic configuration of a dam communication system according to an embodiment.

[0013] The dam control system comprises two discharge operation devices 1a and 1b, a training device 2 and an information input / provision device 3 connected to an information system LAN 9, an input / output device 4 connected to a control system LAN 8, a remote manual operation device 5, a machine side panel 6, and gate equipment 7.

[0014] The discharge operation devices 1a and 1b are connected to a control system LAN 8 and an information system LAN 9. The input / output device 4 and the remote manual operation device 5 are connected to the control system LAN 8 on one hand and to a machine-side panel 6 on the other hand. The machine-side panel 6 is connected to the gate equipment 7.

[0015] The machine side panel 6 is realized as, for example, a PLC (Programmable Logic Controller), and includes an automatic system machine side panel PLC61 and a manual system machine side panel PLC62.

[0016] The discharge operation devices 1a and 1b are, for example, duplicated devices and are realized by an industrial computer (Factory Automation PC: FA-PC). Here, in the following description, unless there is a need to distinguish between them, the discharge operation devices 1a and 1b will be simply referred to as the discharge operation device 1.

[0017] The discharge operating device 1 can collect and display information necessary for dam management, such as the water level of the dam lake, the water level of the upstream river, and the amount of rainfall, using a telemetry device (not shown). In addition, the discharge operating device 1 outputs operation commands, such as start commands, gate opening commands, gate closing commands, or target opening degrees, to the input / output device 4 via the control system LAN 8 in response to operations by an operator or dam manager. For example, when the gate equipment 7 is automatically controlled, the discharge operating device 1 receives input of the target opening degree from the operator and outputs an operation command including the target opening degree to the input / output device 4.

[0018] The training device 2 is a device that allows operators to learn flood-related tasks, such as formulating discharge plans at the start of discharge and determining when to switch between discharge methods. The training device 2 is implemented, for example, as an FA-PC. The training device 2 can assume various rainfall amounts and increases or decreases in inflow to the dam, and allows operators to input target discharge volumes for each future release time based on the assumed values. The training device 2 also has the function of selecting a future discharge method and simulating how the reservoir's behavior and the corresponding status of inflow and outflow volumes will change if the dam is operated using this target discharge volume and discharge method.

[0019] The information input / providing device 3 is a device that acquires data related to dam management, such as inflow volume and rainfall volume, from various observation devices. The information input / providing device 3 is realized as an FA-PC. The information input / providing device 3 may also function as a communication device that transmits information to external organizations such as river bureaus and regional development bureaus via a network.

[0020] The input / output device 4 is a device that relays between the automatic system machine side panel PLC61 of the machine side panel 6 and the discharge operation device 1. For example, the input / output device 4 transmits an operation command received from the discharge operation device 1 to the machine side panel 6. The input / output device 4 also transmits a notification received from the machine side panel 6 to the discharge operation device 1.

[0021] The remote manual operation device 5 is a device that relays between the manual system machine side panel PLC 62 of the machine side panel 6 and the discharge operation device 1. When manually controlling the gate equipment 7, an operator performs open / close / stop operations from the operation unit of the remote manual operation device 5, and the remote manual operation device 5 outputs open / close / stop commands to the manual system machine side panel PLC 62 in accordance with these operations.

[0022] The automatic system machine side panel PLC 61 outputs a drive command to the gate equipment 7 based on the operation command received from the input / output device 4. In addition, the automatic system machine side panel PLC 61 may receive information on the opening degree of the gate equipment 7 from an opening degree meter provided in the gate equipment 7, for example.

[0023] The manual system machine side panel PLC 62 outputs a drive command to the gate equipment 7 based on the open / close / stop command received from the remote manual operation device 5. In addition, for example, the manual system machine side panel PLC 62 may receive information about the opening degree of the gate equipment 7 from an opening degree meter.

[0024] The gate equipment 7 is installed at the dam and adjusts the amount of water discharged from the dam. The gate equipment 7 can open, close, or stop the gate based on a drive command from the on-site panel 6.

[0025] FIG. 2 is a block diagram showing an example of the configuration of the training device 2 according to the embodiment. As shown in Figure 2, the training device 2 includes a control unit 21, a program storage unit 22, a data storage unit 23, a communication interface 24, and an input / output interface 25. The control unit 21, the program storage unit 22, the data storage unit 23, the communication interface 24, and the input / output interface 25 are communicatively connected to one another via a bus. Furthermore, the communication interface 24 is communicatively connected to the discharge operation device 1 and the information input / providing device 3 via an information LAN 9. Furthermore, the input / output interface 25 is communicatively connected to an input device 26 and an output device 27.

[0026] The control unit 21 controls the training device 2. The control unit 21 includes a hardware processor such as a central processing unit (CPU). For example, the control unit 21 may be an integrated circuit capable of executing various programs.

[0027] The program storage unit 22 may use, as a storage medium, a combination of nonvolatile memories that can be written to and read from at any time, such as an EPROM (Erasable Programmable Read Only Memory), an HDD (Hard Disk Drive), or an SSD (Solid State Drive), and a nonvolatile memory such as a ROM (Read Only Memory). The program storage unit 22 stores programs necessary for executing various processes. That is, the control unit 21 can realize various controls and operations by reading and executing the programs stored in the program storage unit 22.

[0028] The data storage unit 23 is a storage that uses a combination of nonvolatile memory such as a HDD or memory card, which can be written to and read from at any time, and volatile memory such as a RAM (Random Access Memory), as a storage medium. The data storage unit 23 is used to store data acquired and generated in the process of the control unit 21 executing programs and performing various processes.

[0029] The communication interface 24 includes one or more wired or wireless communication modules. For example, the communication interface 24 includes a communication module that is wired to an external device such as the discharge operation device 1 or the information input / providing device 3 via the information LAN 9. In other words, the communication interface 24 may be a general communication interface as long as it can communicate with the external device under the control of the control unit 21 and send and receive various information.

[0030] The input / output interface 25 is connected to the input device 26, the output device 27, etc. The input / output interface 25 is an interface that enables transmission and reception of information between the input device 26 and the output device 27. The input / output interface 25 may be integrated with the communication interface 24. For example, the training device 2 and at least one of the input device 26 and the output device 27 may be wirelessly connected using short-range wireless technology or the like, and various types of information may be transmitted and received using the short-range wireless technology.

[0031] The input device 26 includes, for example, a keyboard, a pointing device, etc., which are used by the operator or dam manager to input various instructions to the training apparatus 2. The input device 26 may also include a reader for reading data to be stored in the program storage unit 22 or the data storage unit 23 from a memory medium such as a USB memory, or a disk device for reading such data from a disk medium.

[0032] The output device 27 includes a display that displays output data to be presented from the training device 2 to the operator or dam manager, and a printer that prints out information displayed on the display.

[0033] Next, the software configuration of the control unit 21 will be described in more detail. The control unit 21 includes a data acquisition unit 211, a prediction data acquisition unit 212, an overlay processing unit 213, an action guideline table acquisition unit 214, a display control unit 215, and an action control unit 216. The data storage unit 23 includes a prediction data storage unit 231, an action guideline table storage unit 232, and a dam quantity data storage unit 233.

[0034] The data acquisition unit 211 acquires dam quantity data. The data acquisition unit 211 acquires dam quantity data, including the dam's water level, water storage volume, inflow volume, and outflow volume, from the dam quantity data storage unit 233 (described later). The dam quantity data may include not only dam data but also various data that can be acquired by the information input / providing device 3. For example, the dam quantity data includes river information acquired by the information input / providing device 3, rainfall around the dam, and the like. For example, the data acquisition unit 211 may acquire dam quantity data for a period specified by an operator. Alternatively, the data acquisition unit 211 may acquire dam quantity data input by the operator to the input device 16. Note that if information around the dam is not stored in the dam quantity data storage unit 233, the data acquisition unit 211 may acquire necessary data from an external organization via the information input / providing device 3.

[0035] The prediction data acquisition unit 212 acquires prediction data. For example, the prediction data acquisition unit 212 acquires prediction data stored in the prediction data storage unit 231. The prediction data acquisition unit 212 may acquire multiple pieces of prediction data in descending order of risk from the prediction data stored in the prediction data storage unit 231 based on the dam quantity data. Alternatively, the prediction data acquisition unit 212 may acquire multiple pieces of prediction data in descending order of risk from the prediction data that is most similar to the current situation based on the dam quantity data.

[0036] The overlay processing unit 213 performs processing for overlaying one of the plurality of pieces of forecast data and the dam quantity data for display. For example, the overlay processing unit 213 overlays one of the plurality of pieces of forecast data received for display on the output device 27 with the dam quantity data. The overlay processing unit 213 then outputs the overlaid data to the display control unit 215. The overlaid data may be data that allows the display control unit (described later) to display a screen that displays one of the pieces of forecast data and the dam quantity data and allows switching to other forecast data using tabs.

[0037] The action guideline table acquisition unit 214 acquires an action guideline table from the action guideline table storage unit 232 (described later). Here, the action guideline table is a rule determined for each dam management company, and is a table indicating what actions the operator should take depending on the dam's status and time. For example, the action guideline table describes what action the operator needs to take after how many minutes from a starting time. The starting time may be any time, such as the date and time when a flood warning is issued or the date and time when the dam's water storage volume exceeds a predetermined amount. In other words, there may be multiple action guideline tables corresponding to the dam quantity data. The action guideline table acquisition unit 214 may acquire an appropriate action guideline table from multiple action guideline tables depending on the dam quantity data (i.e., the current dam status). Furthermore, the action guideline table acquisition unit 214 may input the date and time when the operator should take action into the action guideline table, starting from the date and time when the operator inputs an instruction to start training.

[0038] The display control unit 215 generates display screen data for displaying the superimposed data and the action guideline table on the display of the output device 27, and outputs the generated display screen data to the output device 27.

[0039] The action control unit 216 determines the current situation and the next action that the operator should take based on the action guideline table, the dam quantity data, and the current time.The action control unit 216 then generates a message instructing the operator to take action based on the determination result.The generated message instructing the operator to take action is also displayed on the display of the output device 27 by the display control unit 215.

[0040] FIG. 3 is a block diagram showing an example of the configuration of the discharge operating device 1 according to the embodiment. As shown in Fig. 3, the discharge operating device 1 includes a control unit 11, a program storage unit 12, a data storage unit 13, a communication interface 14, and an input / output interface 15. The control unit 11, the program storage unit 12, the data storage unit 13, the communication interface 14, and the input / output interface 15 are communicatively connected to one another via a bus. Furthermore, the communication interface 14 is communicatively connected to other devices via a control system LAN 8 and an information system LAN 9. Furthermore, the input / output interface 15 is communicatively connected to an input device 16 and an output device 17.

[0041] The control unit 11, program storage unit 12, data storage unit 13, input / output interface 15, input device 16, and output device 17 may have the same hardware configuration as the control unit 21, program storage unit 22, data storage unit 23, input / output interface 25, input device 26, and output device 27 of the training device 2 described with reference to Figure 2. Therefore, a duplicated description will be omitted here.

[0042] The communication interface 14 includes one or more wired or wireless communication modules. For example, the communication interface 14 includes a communication module that establishes a wired or wireless connection with an external device via the control LAN 8 and the information LAN 9. For example, the communication interface 14 may include a wired communication module that establishes a wired connection with an external device such as the input / output device 4. In other words, the communication interface 14 may be a general communication interface as long as it can communicate with an external device under the control of the control unit 11 and send and receive various information.

[0043] Next, the software configuration of the control unit 11 will be described in more detail. The control unit 11 includes a data acquisition unit 111, a prediction data acquisition unit 112, an overlay processing unit 113, an action guideline table acquisition unit 114, a display control unit 115, an action control unit 116, and a prediction calculation unit 117. The data storage unit 13 includes a prediction data storage unit 131, an action guideline table storage unit 132, and a dam quantity data storage unit 133.

[0044] The data acquisition unit 111, the predicted data acquisition unit 112, the overlay processing unit 113, the action guideline table acquisition unit 114, the display control unit 115, the action control unit 116, and the action guideline table storage unit 132 may have the same configuration as the data acquisition unit 211, the predicted data acquisition unit 212, the overlay processing unit 213, the action guideline table acquisition unit 214, the display control unit 215, the action control unit 216, and the action guideline table storage unit 232 of the training device 2 described with reference to Figure 2. Therefore, duplicated explanations will be omitted here.

[0045] The prediction calculation unit 117 calculates prediction data based on the dam quantity data stored in the dam quantity data storage unit 133 or the dam quantity data acquired from each dam observation device. The method for calculating the prediction data may be any common method, and therefore a detailed description thereof will be omitted here. The prediction calculation unit 117 stores the predicted prediction data in the prediction data storage unit 131. The prediction calculation unit 117 may also transmit the prediction data via the communication interface 14 and the information LAN 9. The control unit 21 of the training device 2 stores the received prediction data in the prediction data storage unit 231.

[0046] (operation) FIG. 4 is a flowchart showing an example of a training processing procedure of the training device 2 of the embodiment. The control unit 21 of the training device 2 reads out and executes the program stored in the program storage unit 22, thereby realizing the operations of this flowchart.

[0047] Here, it is assumed that the predicted data storage unit 231 stores a plurality of predicted data predicted by the prediction calculation unit 117.

[0048] This flowchart will be explained as a flowchart of the operation of the training device 2, but the following operations can also be executed by the control unit 11 of the discharge operation device 1. However, since the operations performed by the training device 2 are strictly for training purposes, they do not actually control the gate equipment, but when operations are performed by the discharge operation device 1, if the control unit 11 determines that either the predetermined rainfall or the dam quantities have exceeded the predetermined amount, it will start the following operations and execute gate control.

[0049] This flowchart begins with an operator or dam manager entering an input into the training device to begin training.

[0050] In step ST101, the data acquisition unit 211 acquires dam quantity data from the dam quantity data storage unit 233. The data acquisition unit 211 acquires dam quantity data including the water level, water volume, inflow volume, outflow volume, etc. of the dam.

[0051] The dam quantity data may include not only dam data but also various data that can be acquired by the information input / providing device 3. For example, the data acquisition unit 211 may acquire dam quantity data for a period designated by the operator.

[0052] Alternatively, the data acquisition unit 211 may acquire dam quantity data input by an operator. Here, the dam quantity data acquired from the operator may be all or part of the various data required for training. Note that when the discharge operation device 1 is executed, the data acquisition unit 111 may acquire the current dam quantity data.

[0053] Furthermore, if data such as rainfall amount is not stored in the dam quantity data storage unit 233, the data acquisition unit 211 may acquire necessary data from an external organization via the information input / provision device 3. The data acquisition unit 211 may output the acquired dam quantity data to the data acquisition unit 211, the superposition processing unit 213, and the behavior control unit 216.

[0054] In step ST102, the predicted data acquisition unit 212 acquires predicted data. For example, the data acquisition unit 211 acquires a plurality of predicted data stored in the predicted data storage unit 231.

[0055] The prediction data acquisition unit 212 may acquire multiple pieces of prediction data from the prediction data stored in the prediction data storage unit 231 in descending order of risk based on the dam quantity data. Alternatively, the prediction data acquisition unit 212 may acquire multiple pieces of prediction data in descending order of risk based on the dam quantity data, starting with the prediction data predicted from the data that is closest to the current situation. Note that if the prediction data acquisition unit cannot acquire multiple pieces of prediction data, it is sufficient to acquire at least one piece of prediction data.

[0056] Then, the predicted data acquisition unit 212 outputs the acquired predicted data to the superimposition processing unit 213.

[0057] In step ST103, the overlay processing unit 213 generates overlay data. Processing is performed to overlay one of the multiple prediction data and the dam quantity data for display. For example, the overlay processing unit 213 may perform processing to display the dam quantity data and the prediction data with the highest risk as overlay data. Then, the overlay processing unit 213 outputs the overlay data to the display control unit 215.

[0058] In step ST104, the action guideline table acquisition unit 214 acquires the action guideline table from the action guideline table storage unit 232. The action guideline table acquisition unit 214 acquires the action guideline table from the action guideline table storage unit 232 and inputs the required dates and times into the action guideline table, starting from the date and time when the instruction to start training is input from the operator. For example, if the instruction to start training is received from the operator at 9:00, the action guideline table acquisition unit 214 inputs the date and time when the action should be taken in the action guideline table, starting from 9:00. Then, the action guideline table acquisition unit 214 outputs the input action guideline table to the display control unit 215.

[0059] In step ST105, the display control unit 215 generates display screen data for displaying the superimposed data and the action guideline table on the display of the output device 27. The display screen data may be, for example, screen data that displays the superimposed data and the action guideline table and allows switching between other prediction data among the plurality of prediction data using tabs.

[0060] In step ST106, the display control section 215 outputs the display screen data to the output device 27.

[0061] FIG. 5 is a diagram showing an example of a screen displayed on the display of the output device 27. As shown in Fig. 5(1), the display control unit 215 controls the display of the output device 27 to display the inflow and outflow amounts, which are one of the dam quantity data, superimposed on the predicted data. This enables the operator to control the dam while predicting the future inflow amount.

[0062] Furthermore, the dam quantity data and forecast data may be displayed in chronological order. By displaying the dam quantity data and forecast data in chronological order rather than simply as numbers, past, present, and future values ​​can be visually understood more easily.

[0063] As shown in Fig. 5(2), the display control unit 215 controls the display of the output device 27 so that multiple pieces of predicted data can be switched and displayed. In the example of Fig. 5, predicted data "A" is displayed superimposed on the inflow and outflow amounts, but predicted data such as "B" can also be displayed superimposed on the inflow and outflow amounts.

[0064] As shown in FIG. 5(3), the display control unit 215 controls the display of the output device 27 to display the action guideline table. The current action to be taken may also be highlighted (indicated by diagonal lines in the example of FIG. 5(3)). In addition, the example of FIG. 5(3) shows an example in which the action guideline table is displayed together with the overlay data on one display, but if the output device 27 has multiple displays, the display control unit 215 may control the display to display the overlay data and the action guideline table on separate displays. In this way, by simultaneously displaying the overlay data and the action guideline table on the display, the operator can operate the dam while comparing the action guideline table with the future status of the dam, and can operate the dam while checking the release method that should be selected in the near future.

[0065] As shown in Fig. 5(4), the display control unit 215 controls the display of the output device 27 to display a countdown of the timing of the next action to be taken. The display control unit 215 controls the output device 27 to display the time until the next action to be taken in countdown format based on the action guideline table. This allows the operator to operate the gate control while checking the plan.

[0066] 4, in step ST107, the action control unit 216 determines the action to be taken. The action control unit 216 determines the current situation and the next action to be taken by the operator based on the action guideline table received from the action guideline table acquisition unit 214, the dam situation, and the current time. For example, the action control unit 216 may determine, based on the action guideline table, that the operator needs to control a specific gate at a predetermined time.

[0067] In step ST108, the behavior control unit 216 generates a message instructing the operator to take action. The behavior control unit 216 generates a message instructing the operator to take action based on the determination result. Furthermore, for example, as described above, if the operator determines that a specific gate control is necessary, the behavior control unit 216 may also generate an instruction to display a screen for performing gate control, and include the instruction in the message instructing the operator to take action. The behavior control unit 216 then outputs the message instructing the operator to the display control unit 215.

[0068] In step ST109, the display control unit 215 outputs a message indicating that an action should be taken to the display of the output device 27. For example, based on an instruction to display a screen for performing gate control included in the message indicating that an action should be taken, the display control unit 215 displays screen information for performing gate control on the display of the output device 27. Furthermore, the display control unit 215 controls the display of the output device 27 to display the message indicating that an action should be taken on the screen.

[0069] FIG. 6 is a diagram showing an example of a screen displayed on the display of the output device 27. As shown in Fig. 6, the display control unit 215 controls the display of the output device 27 to display a screen for selecting gate control, i.e., a discharge method. Furthermore, the display control unit 215 controls the display of the output device 27 to display which discharge method should be selected from the discharge methods and an explanation of this discharge method. In this way, the operator can correctly select the discharge method, which is gate control, while checking the message content.

[0070] Returning to FIG. 4, in step ST110, the behavior control unit 216 determines whether all the behaviors have been executed. The behavior control unit 216 determines whether all the behaviors listed in the behavior guideline table have been executed. For example, the behavior control unit 216 may make this determination based on whether an instruction based on the behavior guideline table has been received from the manager. Alternatively, the behavior control unit 216 may make this determination based on the behavior guideline table and the current time. If it is determined that all the behaviors have been executed, the processing ends. On the other hand, if it is determined that not all the behaviors have been executed, the processing returns to step ST107.

[0071] (Operation and effect of the first embodiment) According to the embodiment described above, the operator can perform training based on the action guideline table in accordance with actual actions. Furthermore, the display control unit 215 displays the action guideline table together with the superimposed data in which the prediction data is superimposed on the dam quantity data. This allows the operator to perform gate control while predicting future inflow. Furthermore, the action control unit 216 determines the next action to be performed and notifies the operator of the next action based on the determination result. This allows the operator to perform correct gate control.

[0072] [Second embodiment] Next, a second embodiment will be described. In the second embodiment, the condition determination unit 217 performs a condition determination as to whether an operation command for the training apparatus results in excessive discharge due to the target opening and discharge method.

[0073] (composition) The configuration of the dam control system in the second embodiment may be the same as the configuration of the dam control system described with reference to Figure 1, so a duplicated description will be omitted here. Furthermore, the hardware configurations of the training device 2 and the discharge operation device 1 may be the same as the configurations described with reference to Figures 2 and 3, respectively, so a duplicated description will be omitted here.

[0074] FIG. 7 is a block diagram showing the configuration of a training device 2 in the second embodiment. 7, the software configuration of the training device 2 in the first embodiment differs in that the control unit 21 includes a condition determination unit 217 and a gate control unit 218.

[0075] The condition determination unit 217 determines whether an operation command has been received. It determines whether an operation command including a target gate opening, discharge method, etc. for an operator to change the dam discharge volume, etc. in accordance with the action guideline table has been received. The condition determination unit 217 determines whether excessive discharge is occurring based on the target gate opening and discharge method included in the operation command.

[0076] For example, if the target opening or discharge method exceeds the upper limit value that may result in excessive discharge, the condition determination unit 217 determines that the operation command is not appropriate. On the other hand, if the target opening or discharge method does not exceed the upper limit value that may result in excessive discharge, the condition determination unit 217 determines that the operation command is appropriate. The condition determination unit 217 may also determine whether the operation command is based on a guideline table. Furthermore, the condition determination unit 217 generates a warning message to notify the operator that the operation command is not appropriate.

[0077] In addition to the functions described in the first embodiment, the display control unit 215 may perform control so as to display a warning message on the display of the output device 27.

[0078] (operation) FIG. 8 is a flowchart showing an example of a processing procedure of the training device 2 in the second embodiment. The control unit 21 of the training device 2 reads out and executes the program stored in the program storage unit 22, thereby realizing the operations of this flowchart.

[0079] Steps ST201 to ST206 may be the same as steps ST101 to ST106 described with reference to FIG. 4, and therefore a duplicated description will be omitted here.

[0080] In step ST207, the condition determination unit 217 determines whether or not an operation command has been received. It determines whether or not an operation command including a target gate opening, a discharge method, etc. for the operator to change the dam discharge amount, etc. in accordance with the action guideline table has been received. If an operation command has not been received, the process returns to step ST207. That is, the condition determination unit 217 repeats the determination process of step ST207 until an operation command is received.

[0081] On the other hand, if it is determined that an operation command has been received, the process proceeds to step ST208.

[0082] In step ST208, the condition determination unit 217 determines whether the operation command is appropriate. For example, the condition determination unit 217 determines whether the target opening and discharge method included in the operation command result in excessive discharge. For example, if the target opening or discharge method exceeds the upper limit value that may result in excessive discharge, the condition determination unit 217 determines that the operation command is not appropriate. On the other hand, if the target opening or discharge method does not exceed the upper limit value that may result in excessive discharge, the condition determination unit 217 determines that the operation command is appropriate.

[0083] If it is determined that the operation command is appropriate, the process proceeds to step ST210. On the other hand, if it is determined that the operation command is not appropriate, the process proceeds to step ST209.

[0084] Furthermore, the condition determination unit 217 may determine whether the operation command is based on the action guideline table. For example, if the operation command is an abnormal command that is not listed in the action guideline table, the condition determination unit 217 may determine that the operation command is not appropriate.

[0085] In step ST209, the display control unit 215 outputs a warning message. If it is determined that the operation command is not appropriate, the condition determination unit 217 generates a warning message to inform the operator that the operation command is not appropriate. The warning message may include the reason why the operation command is not appropriate.

[0086] Then, the condition determination unit 217 outputs a warning message to the display control unit 215. The display control unit 215 outputs the warning message to the display of the output device 27, and performs control so that the warning message is displayed on the display.

[0087] Then, the process proceeds to step ST211. That is, if it is determined that the operation command is not appropriate, the process does not execute gate control, which will be described later.

[0088] FIG. 9 is a diagram showing an example of a warning message displayed on the display of the output device 27. As shown in Figure 9, the display control unit 215 may control the display to display a warning message containing a reason such as "The over-discharge limit value has been exceeded. Recalculation is required" above the button that was pressed to set the gate operation.

[0089] In step ST210, the gate control unit 218 executes control. If it is determined that the operation command is appropriate, the condition determination unit 217 outputs the operation command to the gate control unit 218. The gate control unit 218 generates information indicating that gate control has been executed based on the operation command, and outputs the information to the display control unit 215. The display control unit 215 may perform control so that a display indicating that gate control has been executed based on the information is displayed on the display of the output device 27.

[0090] On the other hand, when the process of step ST210 is executed in the discharge operating device 1, the gate control unit of the control unit 11 may output an operation command to the gate equipment 7 through the communication interface 14, the control system LAN 8, and the machine-side panel 6. The gate equipment 7 opens and closes the gate based on the operation command.

[0091] In step ST211, the condition determination unit 217 determines whether all actions have been performed. The condition determination unit 217 determines whether all actions listed in the action guideline table have been performed. For example, the condition determination unit 217 may make the determination based on whether an instruction based on the action guideline table has been received from the administrator. Alternatively, the condition determination unit 217 may make the determination based on the action guideline table and the current time. If it is determined that all actions have been performed, the processing ends. On the other hand, if it is determined that not all actions have been performed, the processing returns to step ST207.

[0092] It goes without saying that step ST211 may be executed by the behavior control section 216 in the same manner as in the first embodiment.

[0093] (Effects of the second embodiment) According to the embodiment described above, the condition determination unit 217 determines whether the operation command is an appropriate action. If it is determined to be incorrect, the display control unit 215 controls the display of the output device 27 to display a warning message with the reason. Based on this reason, the operator can re-input an appropriate operation command, thereby performing correct gate control.

[0094] [Third embodiment] The third embodiment is an embodiment for training operations when it is actually necessary to make a telephone call to relevant departments of various ministries and agencies. In this case, when the training is performed on the training device 2, it is not possible to actually make a telephone call, so a button indicating that a telephone call has been made is pressed. In the third embodiment, an example will be described in which a warning message is displayed if this button is pressed at the wrong time during training. Therefore, the third embodiment is performed on the training device 2.

[0095] (composition) The configuration of the dam control system in the third embodiment may be the same as the configuration of the dam control system described with reference to Figure 1, so a duplicated description will be omitted here. Furthermore, the hardware configurations of the training device 2 and the discharge operation device 1 may be the same as the configurations described with reference to Figures 2 and 3, respectively, so a duplicated description will be omitted here.

[0096] FIG. 10 is a block diagram showing the configuration of a training device 2 according to the third embodiment. The configuration in FIG. 10 differs from the configuration of the training device 2 in the first embodiment in that the control unit 21 includes an error determination unit 219 .

[0097] The error determination unit 219 determines whether an implementation signal has been received. Here, the implementation signal is a signal indicating that some kind of communication has been made to the relevant parties at the required timing. In other words, the implementation signal is a signal indicating whether the operator has taken the required action. For example, the implementation signal is not an action performed by the discharge operation device 1, but a signal output from the input device 26 when a button provided to simulate the action performed by the operator is pressed.

[0098] The error determination unit 219 determines whether the implementation signal has been received at the correct timing. The error determination unit 219 determines whether the implementation signal has been received at the correct timing based on the action guideline table.

[0099] For example, if an implementation signal that is not listed in the action guideline table is received, the error determination unit 219 determines that the implementation signal was received at an incorrect timing. Also, if it determines that the implementation signal was not received at the correct timing, the error determination unit 219 generates a warning message.

[0100] (operation) FIG. 11 is a flowchart showing an example of a processing procedure of the training device 2 in the third embodiment. The control unit 21 of the training device 2 reads out and executes the program stored in the program storage unit 22, thereby realizing the operations of this flowchart.

[0101] Steps ST301 to ST306 may be the same as steps ST101 to ST106 described with reference to FIG. 4, and therefore a duplicated description will be omitted here.

[0102] In step ST307, the error determination unit 219 determines whether an implementation signal has been received. In the training, the operator presses an implementation button, which is assumed to have contacted the relevant parties by telephone in accordance with the action guideline table. The input device 26 may output an implementation signal corresponding to the pressing of the implementation button to the control unit 21.

[0103] The error determination unit 219 determines whether or not an implementation signal output from the input device 26 has been received. Here, the implementation signal is a signal indicating that the operator has taken the required action. If it is determined that an implementation signal has not been received, the process proceeds to step ST310. On the other hand, if it is determined that an implementation signal has been received, the process proceeds to step ST308.

[0104] In step ST308, the error determining section 219 determines whether or not the implementation signal has been received at the correct timing. The error determining section 219 determines whether or not the implementation signal has been received at the correct timing based on the action guideline table.

[0105] For example, if an implementation signal that is not listed in the action guideline table is received, the error determining unit 219 determines that the implementation signal has been received at an incorrect timing. In this case, the process proceeds to step ST309.

[0106] On the other hand, if an action signal corresponding to an action written in the action guideline table at the current time has been received, the error determining unit 219 determines that the action signal has been received at the correct timing. In this case, the process proceeds to step ST310.

[0107] In step ST309, the display control unit 215 outputs a warning message. If it is determined that the implementation signal has not been received at the correct timing, the error determination unit 219 generates a warning message and outputs the warning message to the display control unit 215. The display control unit 215 outputs the warning message to the display of the output device 27 and controls the display to display the warning message. Then, the processing proceeds to step ST310.

[0108] FIG. 12 is a diagram showing an example of a warning message displayed on the display of the output device 27. As shown in FIG. 12, the display control unit 215 may perform control so that a warning message such as "This operation is not performed at the correct timing" is displayed above the execution button that was pressed at the wrong time.

[0109] Steps ST310 to ST314 may be the same as steps ST207 to ST211 described with reference to FIG. 8, and therefore a duplicated description will be omitted here.

[0110] (Operation and effect of the third embodiment) According to the embodiment described above, in training, the error determination unit 219 determines whether the execution button has been pressed at the appropriate time. If it is determined that the execution button has been pressed incorrectly, the display control unit 215 controls the display of the output device 27 to display a warning message. By displaying the warning message, the operator can know that the execution button has not been pressed appropriately.

[0111] [Other embodiments] The present invention is not limited to the above-described embodiment.

[0112] For example, the first, second, and third embodiments can be implemented in combination.

[0113] Furthermore, for example, the display control unit 215 may control the display to display a message about what to do next, and if an incorrect action is taken, to display a warning message on the display.

[0114] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
